DALLAS ― For most Americans, North Korea's routine provocations and threats have been all too familiar, yet distant news happening far away. But this time, things are different.

With the rogue nation's specific threat of dropping missiles on the U.S. territory of Guam, many Americans, put on edge, are reacting with a heightened level of anxiety and concern.

''This is getting very serious,'' said Rob Gonzales, 42, who works at a cellular phone retailer in the suburbs of Dallas. ''I usually don't follow much international news, but this isn't international news anymore. It's become very local for Americans.''

U.S. President Donald Trump and North Korean dictator Kim Jong-un have been trading harsh rhetoric and threats of military attack in recent weeks.

Unlike in the past, Pyongyang has disclosed detailed and specific plans against the U.S.

It announced that a missile strike on Guam will be ready by mid-August through which it plans to launch four intermediate-range missiles into the waters 30 to 40 kilometers off of the small, but militarily strategic Pacific island.

In response, Trump declared that the U.S. military is ''locked and loaded'' and that Kim Jong-un will ''truly regret it and he will regret it fast.''

''We are talking about a real war here, a real nuclear war,'' said Matt Wing, 38, a financial consultant, who has lived in Seoul for a year as an English language instructor. ''I've lived in Seoul so I know that all this threat from North Korea is considered same old. But a major factor that has changed from the past is that we have a different president in the U.S. now.''

Many are raising concerns that Trump's hard-line stance against the totalitarian nation will put the entire country in danger.

According to a new poll, a majority of Americans say they feel ''uneasy'' about North Korea. A CBS News survey of more than 1,000 people showed that more than 70 percent of Americans are worried about the current conflict, while only a third are confident about Trump's ability to handle the situation.

''There is a reason that previous presidents didn't go to war with North Korea,'' said Kiera Cunningham, 45, a middle school teacher. ''It looks like a lot of people are thinking this would be like Iraq or Afghanistan where we just drop bombs and the situation will be over.''

She added, ''A military conflict with North Korea, which has one of the largest armies in the world, will mean a full-scale war. Honestly, I'm very concerned." She also cited rare local news coverage of the North Korean conflict that shows the severity of the situation.

Online, constant updates on Trump and Kim's spat and breaking news coverage continue to draw tens of thousands of comments across the country.

''I live in Hawaii. I'm not happy that we let North Korea advance its weapons program so far enough that it can even reach my island,'' a user named Lisa wrote in response to a news article.

Another user named Robert wrote, ''Anybody else reminded of Japan and Pearl Harbor by all this? Let's just hope history will not repeat itself.''
